Inflatable prosthesis insertable in adjustable brassiere

Abstract

A pair of inflatable prosthesis sacs are insertable in two cup portions of an adjustable brassiere each sac including an elastic foam core formed in between an outer layer and an inner layer made of elastic materials, an inflating device directly connectable with a prosthesis check valve formed on the sac for inflating the sac, and a deflating device formed on the sac for deflating the sac, thereby eliminating an air tube connected between an air pump and a brassiere cup in order for making a compact brassiere for its comfortable wearing.

I claim: 
     
       1. An inflatable prosthesis for insertion in a pocket of a cup portion of a brassiere comprising: an inflatable sac including: an outer layer and an inner layer; said outer and inner layers made of elastic materials and each having an edge portion wherein said layers are attached and bound to each other along said edge portion forming a circumferential peripheral edge portion; said outer layer, said inner layer and said peripheral edge portion defining a sac interior, said sac interior filled with an elastomer form core; said prosthesis further comprising a base extension protruding sidewardly from a side portion of the peripheral edge portion of the inflatable sac, and operatively coupled to a check valve, said check valve for inflating said sac formed in the outer layer of the sac adjacent to the side portion, an inflating means secured to said base extension for inflating said sac; and a venting hole formed in the outer layer of said sac, said venting hole further including a deflating means located therein for deflating the sac. 
     
     
       2. The prosthesis according to claim 1, wherein said inflating means includes an inflating bulb secured on the base extension, said inflating bulb and said base extension circumferentially forming an oval shape, a suction inlet valve formed on an outer end portion of the bulb for sucking air into the bulb, and an adapter formed on an inner portion of the bulb and connectable to said check valve for filling air into the inflatable sac through the adapter and said check valve. 
     
     
       3. The prosthesis according to claim 1, wherein said deflating means includes: a deflating valve body generally cylindrical shaped and inserted in the venting hole in the sac, a valve opening formed in the deflating valve body for venting air outwardly when the deflating means is deflated, a sealing plug connected with a valve stem and protruding outwardly beyond the valve opening, a push button formed on an outermost end of the valve stem for depressing the valve stem and the sealing plug for opening the valve opening for deflating the sac, and a restoring spring disposed about the valve stem urging the push button outwardly to raise the sealing plug for sealing the valve opening, whereby upon depression of the push button, the valve opening is opened to deflate the air in the sac. 
     
     
       4. An inflatable prosthesis for insertion in a pocket of a cup portion of a brassiere comprising: an inflatable sac including an outer layer and an inner layer; each said layer having an edge portion wherein said layers are attached and bound to each other along said edge portion forming a circumferential peripheral edge portion; said outer layer, said inner layer and said peripheral edge portion defining a sac interior, said sac interior filled with a foam core member, and a check valve formed in the sac for connecting an inflating and deflating means to the sac for inflating and deflating the sac; and said inflating and deflating means including: an inflating bulb having a suction check valve formed on a suction end of the bulb for sucking air into the bulb, an inflating check valve formed on an outlet end of the bulb, a fluid tube connectable to the inflating check valve of said bulb, an adapter connectable with the check valve of the sac and secured to said fluid tube for inflating the sac when connecting the adapter with the check valve of the sac, a deflating valve body generally cylindrically shaped and formed on an end portion of the fluid tube, a valve opening formed in the valve body for venting air outwardly when the valve opening is opened, a sealing plug connected with a valve stem and protruding outwardly beyond the valve opening, a push button formed on an outermost end of the valve stem and depressible for lowering the valve stem and the sealing plug for opening the valve opening when deflating the sac, and a restoring spring disposed around the valve stem for urging the push button upwardly, whereby upon a depression of the push button, the valve opening is opened for deflating the sac; and upon raising of the sealing plug, the valve opening is sealed. 
     
     
       5. The inflatable prosthesis according to claim 4, wherein said foam core member is made of polyurethane foam.
